Monomers (M) may be the same as the (a) esters, and the (b) units may be where X is -COO- (the C- atom being attached directly to (A)), -O-, or -CO-; Y is -CH 3  or -C 2 H 5 , and Z is  where R 2  and R 3  are Y, -CH 2 -NR 4 R 5 , -CH 2 CH 2 NR 4 R 5  where R 4  and R 5  are H or C 1-4  alkyl, or -CH 2 CH 2 OR 6  where R 6  is C 1-4  alkyl, or provided that when X is -CO-, Z can also be -NH-CH 2 -CH = CH 2 , and further that -X-Z can be e.g. allyl and/or diethylaminoethyl methacrylate. The other monomers forming the balance of (a) may be acrylic or methacrylic acid or their amides or nitriles, vinylacetate, styrene, α - methylstyrene, vinyl toluene, or 3 - (2 - methacryloxyethyl) - 2,2 - spirocyclohexyloxazolidine. Whichever of (A) or (B) is insoluble in the final organosol may have number av. M.W. 10,000-450,000, and the other, 2000-50,000. Steps (1) and (2) may take place in one or more ester, ketone, and/or aromatic hydrocarbon. (A) and (B) may have a solubility parameter difference of at least 0À5 parameter unit. The organic liquid (L) of the final stable organosol may be a mixture of (i) a poor solvent or poor solvent mixture for the film-forming polymer having mean b.p. 60-200‹ C., and (ii) a good solvent or good solvent mixture for the film-forming polymer having mean b.p. 80-320‹ C.; (ii) being less volatile than (i), and (ii)/(i) wt.-ratio being 40/60 to 70/30. The (b) units may be free of α,#-ethylenic unsaturation between those carbon atoms of (b) which reside in the backbone of (A); and the reaction of step (2) may take place in the organic liquid in which the reaction of step (1) was carried out, e.g. without removing any of the unreacted monomers after step (1). The stable organosol may contain graft polymer (A-B), polymer (A), and polymer (B). Also present may be a plasticizer or a pigment.

Abstract: 341,051. Refrigerating. MAIURI, G. and BOSSINI, R. F., 62A, Kensal Road, North Kensington, London. July 6, 1929, No. 20793. [Class 29.] Absorption systems.-In a continuous-cycle system the refrigerant vapour passes from the upper part of a generator-rectifier vessel 1, 2 to a condenser 15 and the condensate flows through a seal 16 to the evaporator 17, while the weak liquor is heated in a riser pipe 5, 6 and lifted to a separator 7, whence evolved vapour of the absorption medium passes by a pipe 12 to a further condenser 13. The condensed absorption medium flows to the absorber 11. Where an inert gas is employed in the evaporator-absorber side it passes with the evaporated refrigerant through a heated ascending conduit 18 to the condenser 13, the inflow of vapour of the absorption medium serving to facilitate the circulation in the cooled descending conduit 13. The weak liquor flows from the separator 7 to the upper part of the absorber and the strong liquor from the lower part of the absorber to the top of the generator-rectifier through a heat interchanger 9. Excess liquid drains from the evaporator through a pipe 23. A substance such as alcohol, less volatile than the refrigerant (ammonia) may be added to the absorbent (water), to assist in the circulation in the conduits 6, 12, 13. The condensers may be cooled by air or water or by a limited quantity of heat-transfer liquid. The heat of condensation and absorption may be in part used to assist in the heating of the generator-rectifier. In a modification the secondary condenser for the absorption medium may be combined with the absorber, and the upper part of the generator-rectifier may be formed as a coiled tube.

Abstract: 138,143. Cammell, Laird & Co., Carter, Sir G. J., and Gibson, J. H. Dec. 20, 1918. Screw propellers.-Feathering propellers in which blades are mounted in sockets and have a projection which engages a sliding and rotating member on the shaft, and in which there is an axially-moving non-rotating member for actuating the rotating member, are provided with a Michell thrust bearing between the two members and a Bowden-wire or similar control for moving the members. The boss comprises a central core 1 with two cylindrical sockets 3, a tubular crosscasing 6 fitting over the sockets and taking the metallic roots 7 of the blades 8, and an extension 9 which has a cylindrical extreme portion 10. The blades are secured to the casing 7 by keys 17, and the casing has thrust ball-races 14 at the bottom and a steadying-sleeve 15 at the top. Each root 7 has a radial pin 18 passing through a slot in the casing 6. On the casing 10 is a sleeve 21 which slides on and rotates with it. The sleeve 21 has brackets carrying pivot pins 22 through which the radial pins 18 slide. When the sleeve 21 is moved axially, the pins 18 rotate the blades on their axes. An inverted-U shaped member 25 takes over the flange 21<a> of the sleeve 21, which, with pad-pieces, form a Michell thrust bearing between the two. The member 25 has projections 27 which pass through oblique slots 28 in a fixed casing 23 and are attached to Bowdenwire controls 30. On the controls being operated, the sleeve 25 has an axial and angular motion, the axial movement being imparted to the sleeve 21, which in turn rotates the blades. The angle of the pins 18 is such that movement other than positive operation of the controls is prevented by the friction between the surfaces in contact.

Abstract: 376,963. Locks for motor &c. vehicles. NEIMAN, A., 19, Erftstrasse, Cologne, Germany. July 27, 1931, No. 21419. Convention date, July 26, 1930. [Class 44.] A locking bolt for motor-cars, bicycles, &c. to prevent unauthorized use is adapted to be inserted in locking position by a removable key, and to be entirely removed by the key in unlocking. Fig. 1 shows the bolt 5 inserted in registering apertures in the outer tube 1 and steering column 12 of a motor-car. A receiving member 2 formed or clamped &c. on tube 1 has a terminal aperture with lateral slot 13, Fig. 4, leading to an enlarged socket. The bolt 5, shown separate, Fig. 2, has slidably mounted thereon a member 4 with lateral rib 6 conforming in cross section to the above aperture, a compression spring 11 being provided between member 4 and a shoulder on the bolt. A key 9 is adapted to screw into a threaded socket 8 in member 4. The bolt is inserted in locking position, rib 6 passing through slot 13, until member 4 is within the socket, the spring being put in compression by contact of the bolt with the inner surface of column 12. The key is rotated to engage rib 6 behind the lip 3 at the outer end of the socket and is then removed, rib 6 bearing against the lip under action of the spring 11 to retain the bolt in place. To release the column 12, the key is inserted and the device 4, 5 removed by reversal of the above movement. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification, Fig. 5 (Cancelled), applied to the steering tube of a bicycle, the bolt 5<1> having a fixed rib 6<1> which remains in the lateral slot of the entrance aperture 13<1> and holds the bolt against rotation, the bolt being retained by a second projection 6<11> rotatable by the key 9<1> to engage behind the terminal lip of socket member 2<1>. In this modification a spring-plunger contact member 19 mounted in an insulating bush 18 engages the bolt and closes or earths an electric circuit (e.g. the ignition circuit) when the bolt is passed through the bore 16 into the aperture 17 in tube 12<1>. A further modification was described in which the bolt-receiving member is formed on a bearing bush for the steering column of a car, the bush being hinged to a body part of the car. The application to locking a brake &c. lever in either of its two positions was also described. In this case the bolt, when in locking position, bridges a gap between two guide plates and extends across the path of the lever. If desired, the bolt may be made to break an electric circuit when in locking position by arranging the contact plunger to raise a bridging contact from a pair of fixed contacts when engaged and moved by the bolt. This subject-matter does not appear in the Specification as accepted.
